Rivet all cowl hinges in place. Skin stiffeners F1295 L&R have changed and now require more rivets in the firewall shelf. Had to drill extra holes to match hole pattern in stiffeners. Rivet all stiffeners into position. Waiting for Finish kit to be delivered. They were to give me an hours notice on delivery and just got a phone call saying he would be here in ten minutes!! Good thing I was here anyway.
